So earlier today, Halo 4 got its first DLC map-pack. It was originally to be 800 Microsoft Points (10$), but somewhere from the lines of 343 to Microsoft to the servers, someone goofed up resulting in it being downloadable for free, as countless Xboxers (me included) rushed in for free content.
If you got the Limited Edition of H4, you were going to get it free off the bat, and now since Microsoft's said it was their fault and that all of the scavengers can keep the maps, the Limited Editioners have flown into a rage for no compensation. Now there are tons of angry hardcore fans wanting to "boycott the game's multiplayer", and calling Microsoft "greedy" for no compensation (even though they just gave away thousands in free content and could ban all of the people who downloaded it if they want to). Funny stuff.
tl;dr: Accidentally free DLC compels all of the people who paid for it to go apeshit, and it's hilarious.
